The invention discloses a multi-wheel vehicle suspension rigidity consistency change control method, device and equipment, and the method comprises the steps: determining the theoretical change multiple of the suspension rigidity of each wheel according to the maximum change quantity of the suspension rigidity of each wheel and the target change quantity of the suspension rigidity of each wheel in a task cycle, further calculating and determining the expected change multiple of the suspension rigidity of each wheel; and according to the suspension stiffness target variable quantity and the suspension stiffness expected change multiple, the suspension stiffness execution variable quantity of each wheel is determined, then the suspension transient stiffness of each wheel at the current moment is determined, and the time required for changing the suspension transient stiffness of each wheel to the suspension steady-state target stiffness of each wheel is controlled to be consistent. According to the method, the time required by the suspension stiffness of each wheel to the steady-state target stiffness of the suspension is equal, and the problem that the steady-state target stiffness of the suspension of each wheel is executed asynchronously due to the fact that the change speed from the transient stiffness of the suspension of each wheel to the steady-state target stiffness is inconsistent is solved.

    本发明公开了一种多轮车辆悬架刚度一致性变化控制方法、装置及设备,其中,方法包括:根据任务周期内各车轮的悬架刚度最大变化量和各车轮的悬架刚度目标变化量,确定各车轮的悬架刚度理论变化倍数,进而计算确定各车轮的悬架刚度期望变化倍数;根据悬架刚度目标变化量和悬架刚度期望变化倍数,确定各车轮的悬架刚度执行变化量,进而确定各车轮当前时刻的悬架瞬态刚度,控制实现各车轮的悬架瞬态刚度变化至各车轮的悬架稳态目标刚度所需时间一致。本发明保证了各车轮的悬架刚度到底其悬架稳态目标刚度所需的时间均相等,解决了各车轮悬架瞬态刚度变化至其稳态目标刚度的变化快慢不一致导致各车轮的悬架稳态目标刚度执行不同时的问题。
